lle it known that I, 0. F. STEDMAN, of Ravenna, inthe county of Portage, and in-.the State of Ohio,

have invented a certain'neiv and. usefull Improvement in vWatches and I'do 4hereby declare that the lfollowing is a full, clear,l and exact description thereof, reference being had tothe accompanying drawings, end the lettersofreference marked thereon. l I v `In the annexed drawings, making a part of this specification, Figure 1 represents the movement of a ''h-unting-case'American watch, called full plate, orclosemovement, in which' the tunning parts, A, are` .heldby and between two plates, a and b, which are themselves supported and held togethezfby pillar-posts',

d J, thereby leaving the movement open at the edge, between the two plates a and b2 Thcse movements are tted intoa case-frame, B, made open, front and back, lsaid openings beingxclosevd by caps, shutting upon case? frame B. The front openingof the casc'frame B corresponds in" diameter to. thntot', the .front cefalee-plank.

of the movement, 'and the back' opening mrresponds'inlikel manner to the diameter'of the backplate'a of the movement, and has a grooveor space, e, 'in which are adjusted springs forv opening the caps of the case. y

represents a. metallic ring or band,'the inner diameter of which corresponds with the diameterof the back plate a offthe movement, end made with an enlargement or bulge, to correspond'vvith and accommodate the main wheel of the watch, which projects a little beyond the edge of the plate a; The band G is slipped or adjusted around soasto.embrace the movement, o needge resting against the back of thefaceplate 1:, and being just wide enough tn close' the space between the 4plates@ and ,Uand. being bevelle'dhtthe vback Yside'to correspond with the bevellededge e of the case-frameB. It 'ivill be seen 'that the diameter of the movement, at the points where it lits within-v the ,openings of' the case-frame B, is the same whether the band C be adjusted or not.

The 'band C may be held 'i n"place by means of pins or other suitable device, and when so 'placed and held as above described, `completely shields the works from `thedirt'that otherwise might readily find its way thereto through the slot-s or openings4 at thev hinges ot the' caps of thecnse-frame B, ahd where the springs of said caps are adjusted, and thence along the groove e, and'nto the Works atany point between theiplatesa'and j It is obvious that Vthe ring or band C', constructed as 4above described, can be used on any full-plate move.

y'ment of an American witch, without the change or modification of any' p'art ofthe same, or of the 'case thereof, andthe bevel `of the edge, corresponding withthebevel e ofthe ense-trame B, prevents the movement from falling or passing too far through the'bac'ky opening of the case-frame B, and holds it in. place in a steady and secure manner. i y l I Having thus f ully described my invention, what I claim as new, and desire toseeure by'Lette-s Patent,is- The ring or band C, bevelled or matie thin'iat one edge or side, said handv being made narrower than the niovement, and wide enough to cover the space between the plates a and b,- substantially as andjfor'the purposes herein set forth. l

In testimony that I claim the foregoing, Ihave hereunto set my hand, this 18th day of'Mai-ch, 1868.' O. F. STEDMAN.
